Fixed xyz bug in ConfigurationManager

[GiraldoNainggolan]

This pull request fixes a bug in the ConfigurasiManager module of the Magento 2 PhpStorm plugin. Previously, there was an issue with configuration parsing that caused incorrect processing, preventing proper loading. This update ensures that configurations are correctly parsed and loaded without errors. The changes include fixing the parsing logic, adding validation to ensure the retrieved values meet expectations, and improving code readability. To test this update, install the latest version of the plugin, open PhpStorm, navigate to the plugin settings, and verify that configurations load correctly without errors. Additionally, check the parsing process to ensure it runs smoothly without generating unnecessary logs.
